Enterprise capacity drive

The HGST Ultrastar He8 0F23651 is an 8TB 3.5-inch internal hard drive built for server and data-centre workloads. It spins at 7200 RPM with a 128MB cache and connects through a SAS 12Gb/s interface. Helium-filled HelioSeal technology and a 7Stac design deliver high capacity in the standard form factor.

33% capacity gain over 6TB

Compared with 6TB air-filled drives this model adds 33% more storage while cutting idle power by 23% and improving power efficiency by 44% in Watts per TB. The 12Gb/s SAS link ensures compatibility with next-generation data-centre controllers. Average seek time is 8.5ms and average latency is 4.16ms.

Suits hyperscale and distributed storage

Designed for cloud, hyperscale and massive scale-out environments running distributed file systems such as Ceph or Hadoop. Buyers needing SATA-only connectivity or a smaller 2.5-inch form factor should look elsewhere. Secure erase and self-encrypting drive options are available for deployments that require them.

Questions sur cet article

Will the 3.5-inch form factor with 26.1mm height fit my standard server drive bay?

Yes, the drive uses a standard 3.5-inch form factor measuring 147mm long, 101.6mm wide and 26.1mm high, matching common server bays.

What is the correct way to connect the SAS 12Gb/s interface and the step installers often miss?

Attach a SAS 12Gb/s cable to the drive's dual-port connector and ensure the backplane or controller also runs at 12Gb/s; the common error is using a 6Gb/s link which halves the bus speed.

When should I expect to replace the drive given its 2M hour MTBF rating?

The 2M hour MTBF rating indicates high reliability for continuous enterprise use; plan replacement based on your workload and SMART monitoring rather than a fixed calendar interval.
